Title: Water-soluble complexes of optical brighteners and quaternary ammonium compounds which are substantially free from unwanted salts
Inventor: ZHAO XIAODONG EDWARD
IPC: C09D7/63
Filed: 1999-04-14
Abstract: This invention relates to water-soluble complexes of optical brighteners with quaternary ammonium compounds which are substantially free from unwanted salts. Such complexes are formed through ionic bonds formed between the two compounds. The inventive complexes are then removed of substantially all excess unwanted salt so as to obtain an optical brightener compound which easily solubilizes within, dispenses from, and exhibits excellent compatibility with standard detergent and softener compositions, which exhibits the desired degree of affinity for various substrate surfaces, including textile, paper, wood, and plastics, as well as within leak detector formulations, and which provides a desired accumulation effect on substrate surfaces upon repeated treatments. Such inventive complexes can also be utilized to whiten thermoplastics and thermosets. Furthermore, this invention also concerns methods of making and utilizing such inventive optical brightening complexes.

Title: System and method for reducing call dropping rates in a multi-beam communication system
Inventor: BUTLER BRIAN
IPC: H04W48/08
Filed: 1999-07-21
Abstract: Method for reducing call dropping rates in a multi-beam communication system  that includes a user terminal, a gateway, and a plurality of beam sources projecting a plurality of beams, and where a link between the user terminal and the gateway is established on one or more beams. The method relies on a messaging protocol between the gateway and the user. Based on messages sent from the user to the gateway, preferably on a preselected periodic basis, th e gateway determines the more desirable beam(s) for transmitting to the user. The messages sent from the user to the gateway contain values representing beam strengths as measured at the user. The gateway uses the user measured beam strengths to select the beams that should be used for the user. The bea ms to be used are the beams that will decrease the call dropping rates and provide a desired level of beam source diversity.

Title: Frame based quality of service
Inventor: BARBAS STEVE N
IPC: H04L12/56
Filed: 1999-10-26
Abstract: A system and method for providing QoS levels to received data units, such as  ATM cells and/or Frames Relay Frames (16). A QoS level associated with a virtual connection (22) is supported through allocation and management of resources used to process data units received over the connection. Resources  used to support QoS levels are assigned to groups of connections (22) referr ed to as "QoS groups". Resources used to support one group of connections (22) may be isolated from resources supporting other connections. When a connecti on is established, if a QoS group exists having the QoS level of the new connection, the connection may be added to that QoS group. Similarly, where the QoS levels for multiple connections must be modified, if those connectio ns are within a single QoS group, then modification of the QoS level for that group would advantageously result in modification of the QoS for each virtua l connection within the QoS group.

Title: System and method of mapping between software objects and structured language element based documents
Inventor: WARFIELD JAY W
IPC: G06F40/143
Filed: 2001-06-07
Abstract: A method and system that provides a common framework for mapping between a document (e.g. an XML document) and a software object (e.g. a Java object).  The framework uses a handler that masks how a property is obtained for mapping. This results in mapping code that has a common appearance for both directions of mapping. A mapping between elements of an XML document and the properties of a Java object is contained in a mapper.  A mapper maps from the XML document to an object using a parser (such as DOM or SAX).  Mapping in the other direction (Java to XML) requires that the elements of the XML document be built in a particular order to ensure validity of the resulting XML document. The present invention builds an XML template document using JSP, for example. Using JSP based templates enables tags of the document to be written in the JSP, with callbacks to get element and attribute values. Further, content can be directed to a buffer, or directly to a response stream of a servlet.

Title: Method for automatically activating call forwarding when a mobile unit comes into service
Inventor: SANDS PHILLIP MICHAEL
IPC: H04M1/00
Filed: 2001-07-04
Abstract: The present invention provides a method for providing automatic call-forwarding to a mobile unit.      The mobile unit is registered as an automatic call-forwarding number for a first phone. The first phone can be a landline phone or a wireless phone. Upon detection of the mobile unit coming into service, calls intended for the first phone are automatically forwarded to the mobile phone. This call-forwarding occurs automatically without further input from a user. Upon detection of the mobile unit going out of service, such as when the mobile unit powers off or leaves the service area of the wireless service provider, the automatic call forwarding to the mobile phone is terminated.
Patent CA-2353674-A1 (CA)
Inventor: HOUDE MICHEL
IPC: H04W8/26
Filed: 1999-11-02
Abstract: There is disclosed a system and method for over the air (OTA) activation of a mobile station (114) in a wireless telecommunications network (10). During activation, a network OTA processor (12) requests the data configuration of the mobile station. The mobile station may issue a challenge the OTA processor and in so doing transmits a challenge message including certain mobile station parameters and a code lock indicator to the OTA processor. The OTA activation processor determines if a new or first code lock parameter has been forwarded to the OTA activation processor by the network for the code lock indicator. If so, the OTA activation processor includes the first code lock parameter in a challenge message forwarded to the authentication center (22) for processing a response to be validated by the mobile station. If not, the OTA activator forwards the challenge message to the home location (20) register that has previously stored the code lock parameter. The home location register substitutes the stored code lock parameter for the code lock indicator and forwards the challenge message so revised to the authentication center for processing. The authentication center uses a code lock parameter comprising one of the Shared Secret Data Challenge (SSD_C) and Shared Secret Data Subsidy (SSD_S) security locks. The OTA activation processor is capable of instructing the authentication center to generate new code lock parameters and instructing the home location register to commit to these new operating parameters.

Abstract: A balanced dipole antenna (600) for a mo-bile phone comprises a radiator element (604) and a counterpoise (608), both formed of a con-ducting material. The counterpoise is electrically isolated from the ground plane of a printed wire board (PWB) (612) of the mobile phone. A matching network, for example, a balun (616, 900, 1000, 1100), provides balanced current to the dipole antenna, resulting in a symmetric radi-ation pattern. The balanced dipole antenna (600) allows superior performance over conventional antennas found in mobile phones today by en-abling a user of a mobile phone to communicate effectively and uniformly in all directions, that is, 360 degrees.
